To (ZZZ whom it may concern:

Be it known that ii. lVILL-IAM J. VAN smm, a citizen of the United States, residing at Chicago, in the county of Cook and the State of Illinois, have invented certain new and useful. Improvements in Hair-Cutters, of which the following is a specification.

This invention relates to iuu rovements in hair cutters more specifically to the power mechanism for actuating the same, and one of the objects of the invention is to provide an improved, simple compact and convenient arrangement of the parts whereby the device may be easily manipulated by the barber. and which will at the same time be cii cctivo and ciiicicnt in opera- 4,. c1011..

A further ob cct is to provide improved means whereby access maybe readily had to the parts, and'at the same time to provide a structure embodying a bearing; having a rotatable shaft mounted therein and means whereby the bearing: will be air cooled so as not to heat the hand of the operator.

To the attainment of these ends and the accolnplisluucnt of other new and useful. objects as will appear, the invention consists in the features of 110W5lty in substantially the construction, combination and arangement of the several parts hercinaflcr more fully dcscribcd and claimed and shown in the accompanying drawings illustrating; this invcntimi, and in which- Figure 1 is a top plan view of an improved dcvicc of this character constructed in accordance with the principles of this invention.

Fig. 2 is a longitudinal sectional view as taken on line 2-2, Fig. 1.

Fig. 3 is a detail top plan, view of the hearing: member.

"Fig. 4 is a horizontal sectional view of the bearing u'icmhcr and with other parts of the mcchanism removed.

Fig. 5 is a detail scctionai view on line 5-4"), Fig. 1.

Fig. 6 is a detail line 6-43, Fig. 1.

Fig. 7 is a sidc clcvation of lever for one of tho, cutters.

Fig. 8 is a top plan vicw of the parts shown in Fig. 7.

In the drawings the hcad of the clipper is of the ordinary and well known construction now in use comprising a knife 10 havscctional view tukcn on the. operating ing teeth 11 along one edge, and a cooperate ing lmifc 12 slidably mounted upon the lmife 10 and having teeth 13 along one edge, cooperating with the teeth 11. Projecting upwardly from the cutter 10 is a stud 14 upon which is mounted an oscillating member 15 which is connected with the cutter 12 so as to impart thereto a motion relative to the cutter 10. Connected with this member 15 and forming a part thereof is a lever 16 one end of wnich is preferably bent at an angle thereto and the bent extremity is bifurcated as at 17 for a purpose to be set forth. This element 16 may be connected Wit-lithe element 15 in any desired or suitable manner and as shown in Fig. 4, may comprise a pin or rivet 18 while the form as shown in Figs. 7 and 8 may comprise spaced depending cars 19 arranged at the forward end thereof and adapted to stand astride of the element 15.

. The stud 14 projects through the elements 15 and 16 and terminates in a threaded extremity to receive a thumb nut 20, which latter is adapted to hold a cap member 21 in position. This cap member is provided with an opening through which the stud 14 passes and the mcmbcr extends over the cutter 12 and also the element 15, the element 16 passing between the cap 21 and the rear portion of the. fiXcd cutter. The thumb nut is provided for the purpose of holding the parts together and there is interposed between the thumb nut and the cap, a spring washer 22 so as tohold the parts under tension. and in order to limit the adjustment of the nut 20 in one direction and .thereby control the tightening of the cap upon the cutter shaft so that it cannot be tightened .to too great an extent, the cap is provided with a recessed portion surrounding the opening; thcrcthrough and the thumb nut is provided with a reduced extremity 24 adapted to enter the recess 23 and abut the shoulder formed thereby so that the nut can be secured upon the stud 14 only to a predetermined extent.

A handlev 25 is connected with the cutter 10 and is of the ordinary and well known shapc. A bearing member 26 is connected with the handle 25 in-any desired or suitable manner such as by means of the fastening dcviccs 2.7. and the hearing member is providcd with a bearing 28 extending longitudinally thcrcthrough. The inner end or the member 26 is provided with an enlarge ment- 29 to form a shoulder 30. Rotatably mounted in the bearing is a shaft 31 having connected with one extremity thereof a, worm 32 which is located, within the en largement 29 and which latter forms a chamber for the worm. The worm isconnected withthe shaft in any suitable manner and is oia diameter siightly'larger thanthe diameter of the bearing 28 so as to form a shoulder adapted to abut the shoulder 30. The end of the chamber 25) in alinement with the end 0? the shaft 31 is open and a bearingmembeflfii having a hardened bearing projection 34 is detachable secured inthe end of the member 26 so that the end of: the shaft 31 will rest against the projection 34: and this member 33 together with theishoulder will hold the shaft ,31 against an axial or longitudinal shifting movement of the shaft within its bearing. The bearing member 33 may be held against accidental displacement in any suitable manner such as by means'of a fastening device 35. The chamber 2Qis provided with a laterally projecting portion "36 communicating therewithand this portion is, provided with a stud or projection 37 connected to and extending from one of the walls of the chamber. 'Rotatably mounted upon this stud 37 is a worm gear 38 which meshes with the Worm'SQ and the portion 36 of the chamber 29 is provided with an opening by means of which ready access maybe had to the parts, and this opening is closed by a suitable closure 39 provided with an ear or extension 40, adapted to be seated in a recess ii in the member 26, and held in position by a suitable fastoning device d2,

The wall of the portion 36 of the chamber 29 is provided with a slot 43 into which the bifurcated extremity of the lever 16 is adapted to project, and .slidably mounted within the bifurcation Not the elen'ient 16 is a block 44 which is pivotally mounted upon a stud 4-5 projectinglaterally and-eccentrically from the Worm gear 38.

Thus it will be seen that when the shaft 31 is rotated the worm gear connection will oscillate the lever 16 and impart a sliding movement to the cutter 12 with relation to the cutter 11. The threads on the worm are so arranged with respect to the'worm gear 38 that during the operation of the shaft, these threads will tend to hold the worm gear 38 against accidental displacement. By the provision of the chamberZl) with the enlargement '36, it will be manifest that-this chamber will form a grease Well for maintaining the parts lubricated, the slot 43 being placed 'mijiacent the top of the chamlmr will prevent the grease from flowlug out of. the slot. it will also be manifest that the removable element 33 permits ready access to the end or" shaft" exterior surface of the bearing member 26 is so shaped that it will be spaced from the handle members 25--46 and thereby form ancn'culation passages between the handles and the bearing member so that the bearing member will be air cooled and obviates the necessity of the operator grasping the bean ing member to hold the implement, and which would by means of the rotation of the shaft 31, cause the operators hand to become heated by the transmission of heat. from the bearing member 26.-

An oil hole 48 provided with a suitable closure may be provided in the bearing member for the shaft 31;.

In order to operate the shaft, there is provided a flexible casin 49 having a reduccd' extremity 50 provi ed with a circumferential open groove 51. This reduced port'ou 50 18 adapted to be inserted in the free extremity of the bearing member 26 and is held against displacement by means of a suitable fastening device such as a pin passing through a suitable opening in the bearing member-and which pin is held in position by means of a spring 53 and a nut 54. A flexible driving shaft 55 is the operation the bearing member may be again secured in position on the handle and the o )erative connection between the parts reesta lished.
